i need the answer quickly
P.6 Carbon dioxide gas enters a water-cooled compressor at the initial conditions Pı =15 (psia) and T1 = 50 (°F) and is discharged at the final conditions P2 =520 (psia) and T2= 200 (°F). The entering CO2 flows through a 4 in-diameter pipe with a velocity of 20(fi)(s)"', and is discharged through a 1 in-diameter pipe. The shaft work supplied to the compressor is 5360 (Btu)(mole)*'. What is the heat-transfer rate from the compressor in kW? H1 = 307 (Btu)(mole)*! VI = 0.5774 m3 kg H2 = 330 ( Btu)(mole)! V2 = 0.0175 m3 kg'.
